This is true, but look it's not like Bernie Sanders is a relatively unknown candidate. He had a high profile run four years ago, has been one of the frontrunners in this one, and his head to head numbers against Trump haven't dipped at all. The thing about Sanders is the more exposure he gets, the more people like him. His message is a popular one, and he's great at giving it. I just don't buy that that is somehow going to turn into a fatal flaw six months from now.
his numbers in swing states are inferior to other options
